PHOTOGRAPHlC-PLATE HOLDER.

SEQEEGIEICA'TION forming part of Letters Patent No. 681,920, datedSeptember 8, 1901.

Application filed February 16, 1901. Serial No. 47,582. (No model.)

To all whom, at may concern.-

Be it known that I, ARTHUR 0. LA MAY, a citizen of the United States,and a resident of Rochester, in the county of Monroe and State of NewYork, have invented a new and Improved Photographic-Plate Holder, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in photographic plate or filmholders; and the object is to provide a holder having a simple device bymeans of which it may be readily adapted for holding plates or films ofdifferent sizes.

I will describe a photographic-plate holder embodying my invention andthen point out the novel features in the appended claims. Reference isto be had to the accompanying drawings, forminga part of thisspecification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figures 1 and 2 are views of opposite sides of a plate-holder embodyingmy invention with the slides removed. Fig. 3 is a section on the line a:of Fig. 1. Fig. 4 is a perspective view of a spring-clip employed. Fig.5 is a perspective view of a corner-clip employed. Fig. 6 is a plan viewshowing a kit with my invention applied thereto, the same being arrangedin an ordinary plate-holder. Fig. 7 is a section on theline y 3 of Fig.(3, and Figs. 8 and 9 are perspective views of modified forms of clipsemployed.

Referring to the drawings, 1 designates the plate-holder frame, and 2 3the opposite slides therefor, arranged in the ordinary manner. Arrangedin the frame are two septums 4 5, consisting of any suitable materialand arranged to spring slightly apart. Each septum is provided near oneend with a series of alined openings 6 and near the other end withopposite openings 7, variously spaced apart and adapted to receivecorner-clips S for the different widths of plates, while the openings 6are designed to receive spring-clips 9 for engaging with the end of theplate. It will be noted that the openings 6 of one septum are arrangedat the end thereof opposite to the openings 6 of the other septum, and

the openings 7 are correspondingly arranged, so as to prevent anypossible passing of light through the openings in the two septums whenthe plate or film is exposed. The corner-clips 8 have shank portions 10for passing through the openings 7 and engaging against the under sideof the septum, and they have also upwardly-extended portions 11 forengaging against the end of a plate, forwardly-project ing portions 12for engaging on the upper surface of the plate, and cornerpieces 13 forengaging against the sides of the plate near the corners. Thespring-clip 9 has a shank portion 1st for engaging underneath the septumand lugs 15 at the ends of the spring-clip for engaging upon the uppersurface of the plate. In operation the opposite corner-clips S will beplaced in opposite openings 7 and the spring-clip engaged in one of theopenings 6, depending upon the size of the plate or film to be supportedin the holder. It will be noted in Figs. 1 and 2 that different-sizedplates may be supported in opposite sides of the frame.

In Figs. (3 and 7 I have shown a septum 16, of any suitablematerialsuch, for instance, as metal-which may be termed a kit, as it isdesigned to be placed against the septum 1'7, ordinarily fixed in aplate-holder. This septum 16 has T-shaped openings 18, arranged in aline at one end, while at the other end T-shaped opposite openings 19are formed. A spring-clip 20, used in connection with this septum-kit,has a shank portion 21, designed to pass through the wider portion ofthe T- shaped openings 18 and underneath the septum, while a portion 22of said shank is designed to be engaged upon the outer or upper surfaceof said septum, as clearly indicated in the drawings. The corner-clips23 for this septum are formed in their body portions substantially likethe corner-clips first described; but they have a shank portion 2a forpassing through the wider portions of the openings 19 and engagingunderneath the septum and lug portions 25 for engaging against the outersurface of the septum.

It will be seen by my invention that a plateholder of a given size maybe adapted to hold plates .of a smaller size and that the adjustmentsmay be very quickly made. The septum 16 will be held in place by theordinary means employed for holding a plate or film in the frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patentother end, the said opposite openings of one 3 septumbeing arranged at the opposite end from that of the opposite openings inthe other septum, a spring-clip for engaging in any one of the alinedopenings, and cornerclips for engaging in opposite openings,substantially as specified.

3. In a photographic-plate holder, a septum having openings, aspring-clip having a shank portion to pass through an opening and toengage against the inner side of the septum, and corner-clips havingshank portions to engage against the inner side of the septum,substantially as specified. I

4:. In a photographic-plate holder, a septum having openings andcorner-clips, each corner-clip having a shank portion, a portion toengage against the end of a plate, a portion to engage upon the outersurface of the plate, and a portion for engaging with the side edge ofthe plate, substantially as specified.

In testimony whereof I have signed my name to this specification inthe'presence of two subscribing witnesses.

ARTHUR 0. LA MAY.
